The Mobulidae are zooplanktivorous elasmobranchs comprising two recognized species of
manta rays (Manta spp.) and nine recognized species of devil rays (Mobula spp.). They are …

This text, written by a leading researcher in the field, describes the origin and formation of
lakes in order to give context to the question of how lacustrine deposits form. It explains the …

Background One of the main explanations for the stunning diversity of teleost fishes (~
29,000 species, nearly half of all vertebrates) is that a fish-specific whole-genome …

Fishes include more than half of all living animals with backbones, but large‐scale
palaeobiological patterns in this assemblage have not received the same attention as those …

Sharks and rays are thought to have a large number of independent origins of live–bearing.
We examined evolutionary transitions to live–bearing and maternal input to embryos in this …

With our increasing ability for generating whole-genome sequences, comparative analysis
of whole genomes has become a powerful tool for understanding the structure, function, and …

Mass extinctions are recognized through the study of fossil groups across event horizons,
and from analyses of long-term trends in taxonomic richness and diversity. Both approaches …

Owing to their phylogenetic position, cartilaginous fishes (sharks, rays, skates, and
chimaeras) provide a critical reference for our understanding of vertebrate genome …

Chondrichthyan fishes are probably the most successful of all fishes if success is measured
in terms of historical endurance. Indeed, they have survived the mass extinctions of the last …

A review of the paleontological literature shows that the early dates of appearance of
Lissamphibia recently inferred from molecular data do not favor an origin of extant …
